Every carbon compliance deadline facing Indian enterprises, in chronological order. Two are already live. The rest have dates on them.
Each row gives the framework, what it requires, and who it binds. Dates verified 16 August 2026.
| Date | Framework | What it requires | Who it binds |
|---|---|---|---|
| 1 Jan 2026 | CBAM | Definitive period began. Embedded emissions now carry a price at the EU border. | Carbon-priced exporters |
| 31 Jul 2026 | CCTS | First annual emissions report due to BEE, for roughly 490 obligated entities across seven notified sectors. | Listed companies |
| 31 Jan 2027 | SBTi | Corporate Net-Zero Standard V2.0 takes effect. Mandatory data assurance, and every Scope 3 category at 5 percent or more. | Listed companies, financial institutions |
| 18 Feb 2027 | Battery Passport | EU Digital Battery Passport goes live for EV, LMT and industrial batteries above 2 kWh. | OEM supply chains |
| FY2026-27 | BRSR Core | Assessment or assurance reaches the top 1,000 listed entities. | Listed companies, financial institutions |
| 30 Sep 2027 | CBAM | First declaration due, covering calendar-year 2026 imports. The data you need was generated last year. | Carbon-priced exporters, OEM supply chains |
| 31 Jan 2028 | SBTi | V1.3.1 submissions close. From here, V2.0 is the only route. | Listed companies, financial institutions |
| Undated | India Climate Finance Taxonomy | Drafted, not yet notified. On notification, every lender must classify its entire loan book. The largest unfired trigger in Indian BFSI. | Financial institutions |
All eight resolve to the same underlying question: can you produce the source document behind the number. That is what Carbon-OS is built to do.
BRSR Core assessment or assurance reaches the top 1,000 listed entities in FY2026-27. It is the assured subset of the wider Business Responsibility and Sustainability Report, so the numbers inside it have to carry an evidence trail an assurance provider can follow.
The CBAM definitive period began on 1 January 2026. From that date embedded emissions carry a price at the EU border, so the emissions data behind a consignment became a commercial input rather than a reporting formality.
The first CBAM declaration is due on 30 September 2027, covering calendar-year 2026 imports. The data it relies on was generated in the year before it is filed, which is why exporters need consignment-level records in place well ahead of the deadline.
The first annual CCTS emissions report is due to the Bureau of Energy Efficiency on 31 July 2026. It applies to roughly 490 obligated entities across seven notified sectors.
SBTi Corporate Net-Zero Standard V2.0 takes effect on 31 January 2027. It brings mandatory data assurance, and it requires every Scope 3 category that accounts for 5 percent or more of the inventory.
SBTi V1.3.1 submissions close on 31 January 2028. From that point V2.0 is the only route to a validated target.
The EU Digital Battery Passport goes live on 18 February 2027. It covers EV, LMT and industrial batteries above 2 kWh, which pushes per-part carbon data collection down into OEM supply chains.
The India Climate Finance Taxonomy has been drafted but not yet notified, so it carries no date. On notification, every lender must classify its entire loan book, which makes it the largest unfired trigger in Indian BFSI.
